Wrist Pin/Rod Bushing Tolerance Measurement

In speaking with a machine shop today, the owner pointed out that the "small ends" rarely see much wear and although they do measure them, rarely do they find the "small end" bushings out of tolerance. His comment was that as long as you see an even crosshatch from the previous build, you're good.

I don't have a micrometer or bore guage, I do have "feelers," a dial guage, vernier calipers and plastigage. Is there a way to measure for myself if the pins (new JE pins) are in tolerance with the wrist pin bushings?

Getting down to the machine shop is a PITA due to my location and work.
